The ECOVACS DEEBOT T90 PRO OMNI is a robot vacuum and mop built around one idea: the mop should clean itself while it works. A single roller replaces the usual pair of spinning pads, and a large station takes care of the messy jobs afterward.
This page draws on the brand’s spec sheet and published policies, plus two independent test write-ups. It is a research-based look, not a hands-on test. The goal is to show who will be happy with this robot and who should look elsewhere.
The short version: independent testers rated the mopping and pet-hair pickup highly, and found navigation reliable overall but not flawless. To see current pricing, browse the ECOVACS storefront on Amazon and look for this model. The link opens Amazon.
What It Is and How It Cleans
Start with what the brand publishes. Every figure below comes from the spec sheet.
- Suction: up to 30,000Pa, with 16 L/s of airflow.
- Mop: the OZMO ROLLER 3.0, a roller about 10.6 inches (27 cm) long that spins at up to 200 RPM.
- Carpet handling: the roller lifts 0.59 inches (15 mm) and suction ramps up. There is no physical carpet cover.
- Height: 95 mm, or about 3.7 inches.
- Battery: 4,000 mAh, with PowerBoost fast charging that adds about 10% in 3 minutes during mop-wash stops.
- Runtime: up to 350 minutes in standard mode, according to the brand.
- Station: a self-service base that bags the dust (2.5 L bag), keeps a 4 L fresh-water tank and a 2.2 L dirty-water tank, and rinses the roller using water heated to 167°F. Hot air then dries it, and cleaning solution is dosed on its own.
- Onboard dustbin: 0.25 L.
- In the box: the robot, the station, a roller, both water tanks, a filter, a dust bag, brushes, and one 260 ml bottle of ECOVACS solution.
The roller is the main difference from most robot mops, which use two round pads that keep wiping with whatever dirt they have already collected. By the brand’s design, jets rinse the roller with fresh water as it turns, and a scraper moves the used water into a tank on the robot, which is meant to keep the surface touching the floor freshly rinsed.
Independent testers were positive about the results. In one test, a dried ketchup stain came off in a single pass and left almost no trace after a second run. Another test scored dried-stain mopping nearly 50% above the average it had measured.
Along walls, the roller can slide out about 0.6 inches (1.5 cm) past the body so edges get mopped too. A soft felt strip is there to protect furniture.

What Stands Out
Mopping drew the strongest praise. One independent reviewer said the roller made several flagship models look pale by comparison.
Independent tests favored its pet-hair handling. ECOVACS says the ZeroTangle 4.0 brush uses airflow channels to steer hair toward the intake rather than letting strands coil around the brush. One test reported a perfect result on a hair-wrap test with 7-inch strands, plus 100% pickup of pet hair, against an 82% average. Another saw no tangling with long test hairs.
The station takes over the chores. By design, it empties the dust, washes and dries the roller, and doses cleaning solution without help. The brand says one bag can last up to 90 days, and that the dirty-water box cleans itself with a propeller spinning at up to 5,000 RPM.
PowerBoost is aimed at larger homes. It restores charge in the short mop-wash stops, and one independent test still showed 75% charge after cleaning 50 square meters. Per task, the brand says it can cover as much as 500 m² (roughly 5,380 sq ft).

Where It Falls Short
Navigation drew the most criticism. This model skips the spinning laser tower. It relies on a front-facing Mini-ToF sensor and an AI camera (AIVI 3D 4.0). That keeps the body slim, but the field of view is narrower.
One independent tester saw it pause to re-aim now and then and brush against slim, dark chair legs, and noted weaker obstacle detection on the trip back to the dock. A second test recorded 23 of 24 obstacles avoided. The first tester also needed a few minutes to correct the room divisions in the app.
There is no mop-only mode. The first tester’s list of cleaning modes runs from an AI mode through vacuum-only and combined vacuum-and-mop to mopping after the vacuum pass.
The onboard bin is small. At 0.25 L, it means more trips back to the station to empty it.
Who It Suits
It makes the most sense for:
- Hard floors such as tile, hardwood and vinyl, where mopping quality matters most.
- Homes with shedding pets and daily hair to deal with.
- Bigger homes where long runs matter more than waiting on the charger.
- Anyone who wants the station to handle water, drying and detergent.
Skip it, or look at a step-up model, if most of your floor is thick carpet, if your furniture is full of thin dark legs, or if you would rather not edit room maps in an app. The T90S PRO OMNI steps up with a built-in cover for carpet and 40,000Pa of suction.

How It Compares
The comparison here uses the Roborock Qrevo Curv 2 Flow, another roller-mop robot. The same independent reviewer tested both, so the notes line up well.
| Feature | T90 PRO OMNI | Qrevo Curv 2 Flow |
|---|---|---|
| Body height | 9.5 cm | 11.9 cm |
| Mapping hardware | Mini-ToF sensor, no laser tower | LiDAR tower on top |
| Cleaning power | 30,000Pa suction | 20,000Pa suction |
| Battery | 4,000 mAh, topped up by PowerBoost | 6,400 mAh |
| Mop roller | OZMO ROLLER 3.0, 27 cm, 200 RPM max | SpiraFlow, 27 cm, 220 RPM |
| Carpet | Lifts 15 mm, no cover | Lifts 15 mm and adds a cover |
| Dirty tank | 2.2 L | 3 L |
| Detergent dosing | Built in | Not included |
| Mop-only mode | Absent | Absent |
Mopping goes to ECOVACS. The tester called the T90’s mopping very good, while the Roborock’s mopping fell short of expectations in the same review. One possible factor is experience: ECOVACS has built roller mops through multiple generations, and this was Roborock’s first.
Navigation goes to Roborock. The reviewer described its spinning LiDAR tower as giving a full view around the robot, with systematic coverage. The T90 pauses to reorient from time to time, and the reviewer noted that obstacle detection is weaker on the return trip to its dock. Both bumped slim dark chair legs in testing.
Height and carpet split the two. The T90 is 2.4 cm shorter, which matters under low sofas and beds. Only the Roborock includes a shield that keeps the damp roller off carpet fibers.
Going by that reviewer’s notes, ECOVACS suits hard-floor homes where mopping comes first. The Roborock suits readers who care more about mapping precision, lots of rugs or a bigger battery.
Before You Buy
Double-check the model name. Two near-twins exist: the T90 PRO OMNI and the plain T90 OMNI. Runtime, charging and features differ between them.
Buy new, from the brand or an authorized seller. ECOVACS ties its 12-month warranty to purchases from itself or its dealers. Its policy names Amazon Resale as one example of resale machines that fall outside coverage.
The policy lists three things that fall outside the warranty: setting up, maintaining or using the robot incorrectly, repairs by unauthorized parties, and parts that ECOVACS did not make or supply. The brand’s own store also sells 1-year and 2-year extended plans.
Returns depend on the seller. ECOVACS’s own store gives 30 days for a refund or exchange, provided you keep the receipt, the box and every accessory. Other retailers set their own terms, so read them on the page where you order.
Check the plug and the footprint. The US station’s heating module is listed at 110V, built for North American outlets. The station with its base measures about 13.3 by 18.1 by 19.7 inches, so measure your spot and find a nearby outlet first.
Quick Questions
Does it work without Wi-Fi?
Partly. The brand says the buttons on the robot can start, pause and stop it. Anything beyond that, including maps, remote control and custom settings, requires an internet connection together with the ECOVACS HOME app.
How loud is it?
An independent test measured about 58 dB, climbing to roughly 68 dB at maximum suction on carpet. ECOVACS quotes 60 dBA for standard cleaning. The station is louder while it empties the dust: 71 dBA on the silent setting and 76 dBA on standard.
How quickly does it charge?
The spec sheet lists 2.5 hours for a full charge. Across most of its robots, ECOVACS gives a wider range of 3 to 5 hours and cautions that the very first charge can take longer.
Can it clean in the dark?
According to ECOVACS, yes. Its robots find their way using sensors, infrared and AI mapping rather than depending on room light.
How often does the station need attention?
The two water tanks are the regular chore: keep the 4 L clean tank topped up and the 2.2 L dirty tank emptied, with the timing depending on home size and settings. The brand quotes up to 90 days per dust bag and 150 days between cleanings of the mop washing tray.
The Verdict
Independent testers’ notes point to a mid-range robot with mopping that rivals pricier models. The weaker points are navigation, as the testers found, and the lack of a mop-only mode.
If clean hard floors are your priority, it fits that brief well. If your home is mostly thick carpet or crowded with thin dark chair legs, look at the step-up T90S PRO OMNI or a LiDAR-based rival first.
